Application filed October 31, 1888. derial No.289,602r (No model.)Patented in Canada October 10,

T0 aZZ whom it may concern.-

Be it known that I, JOHN FRANCIS OBRIEN, of the city and Province ofQuebec, in the Dominion of Canada, have invented certain new and usefulImprovements in Telephone- Addres's Indexes and Advertising Devices,(for which I have obtained Letters Patent in the Dominion of Canada,numbered 29,968, dated October 10, 1888;) and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, in which Figure 1 is afront elevation of my addressindex and advertising medium. Fig. 2 is alike view of the same as when in use, and Fig. 3 is a vertical sectionof Fig. 2.

My invention has for its objectto enable telephone-subscribers toquickly ascertain the call-address of other subscribers by an indexconvenient for reference and to allow of display of advertisements on.the pages of said index without impairing the ready reference to calladdresses.

My invention consists of a board adapted to be hung near a telephone, anindex-book attached to said board and opening briefwise, and springssecured to the verticaledges of the board to hold up the leaves of theindex when raised for reference. The leaves of the index are preferablyattached to a stubback, which is secured to the board. horizontally,

so that a leaf may be conveniently removed and replaced. The front pagescontain the names of subscribers and their callnumbers andthe backs ofthe pages sold to advertisers for displaying their announcements.

A represents a piece of board of any suitble wood or material, shaped tobe pleasing to the eye and provided with a screw-ring B or a hole tohang the same to a fixture at a place convenient to the sight when usingthe telephone. To the outer face of the said board is secured an indexbook 0. The leaves F are alphabetically lettered at the bottom andpreferably attached at top to a stubback D, removably securedhorizontally to about the middle of the board, whereby the book willopen briefwise and the leaves be severably attachable, to allow a leafcontaining obsolete matter to be replaced by another having the desiredannouncement without removing the other leaves. Ordinary brasspaper-fasteners a will be found convenient for this purpose. Above theindex-book is secured to the board at each of its opposite edges aspring F. These springs are so formed that when a leaf or a number ofleaves of the book are raised against the top part of the board thesprings will yield and, reacting, re: tain said leaves until released.subscribers to a telephone. system are inscribed on the front page ofthe leaves, or that side which is exposed to view when at the dropposition, and on the back of said leaves are displayed advertisements orother announcements, which will be observable when referring to thesubscribers names or subjectmatter of the index.

By my invention the inconvenience of the unhandy reference books nowsupplied to telephone-subscribers is obviated, the liability of the bookbeing lost or mislaid is removed, and the difficulty now oftenexperienced in finding a' reference will be overcome and delay andvexation avoided.

I claim as my invention;-

1. A list for telephone-service or like purpose, composed ofseparately-indexed leaves removably secured to a support and having aspring-holder to receive and hold said leaves when opened for reference,substantially as described.

2. The combination of the board A, the alphabetical index-book O,secured thereto briefwise, and the springs E, to hold up the leaves ofsaid index when making a reference, substantially as set forth.

3. The combination, with the board A, hav

ing. springs E, of the index-book O, secured briefwise thereto, saidbook having a stubback D and leaves F, alphabetically arranged andattached removably to said back, substantially as set forth.
